Table of Contents

This documentation area includes functional specifications for
many features supported by the Catalina servlet container
portion of Tomcat. In most cases, these features are not documented in the
underlying Servlet or JSP specifications, so a definition of the expected
correct behavior is important both to implementors of those features, and to
test writers trying to decide what to test.

The functional specifications are divided into the following categories
in the menu (to the left):

Administrative Apps - Overall requirements for supporting an
ability to configure and operate a Tomcat installation through tools,
as well as detailed requirements for the tools themselves.

Internal Servlets - Requirements for Catalina features that are
implemented as internal, container-managed, servlets.

Realm Implementations - Requirements for the implementations of
the org.apache.catalina.Realm interface (providing access to
collections of users, passwords and roles) that are included in the
standard Tomcat distribution.

NOTE - In some cases, the contents of these functional specs has
been "reverse engineered" from existing implementations. This exercise is
still useful, because it provides an introduction to what
Catalina does, without being as concerned with how this is
accomplished.

TODO - Obviously, this area has a long ways to go before
it is complete. Contributions are welcome!
